SONOS not working as before

Hi all,

With the previous Sonos device handler, I could play files from a local samba server using the x-file-cifs protocol in the URI, but that no longer seems supported in the new LAN Websocket device handler. Thus far in my trial & error testing I can only call playTrack() with an HTTP or HTTPS URI.

Has anyone figured out how to pass this new device handler a local samba/cifs URI?

Thanks for help in advance…
